Dear Aneesh V,
In message 4FE8DCE7.7090700@ti.com you wrote:
What is the (non-contrived) problem to which allowing mis-aligned accesses would be a solution?
memcpy() when there is a mismatch in the alignment of source and destination buffers. Let's say the source buffer is 4 byte aligned but the destination buffer is only 2 byte aligned. I believe relaxed alignment requirements will help in writing an accelerated memcpy routine for this case.
If memcpy() has problems with handling such a situation, then clearly memcpy() needs fixing.
Best regards,
Wolfgang Denk
